Specification of Lettersl-"atent. Patented Apr. 16, 1918.

Application filed May 17, 1913, Serial No. 768,240. Renewed September 5, 1917. Serial No. 189,884..

To all whom it may concern.

Be it known that I, RICHARD L. DEzEN- residing at Richmond Hill, Queens county, New York, have invented certain new and useful Improvements in Gas-Meters, of which the following is a full, clear, and exact description.

My invention relates to improvements in gas meters, and has for its object to provide a meter which can be tested and adjusted without disconnecting it from the mains or removing it from the place in which it is installed, with the result that each meter can be tested and adjusted under the conditions to which that particular meter is normally subject.

The following is a description of a meter embodying my invention, reference being had to the accompanying drawings, in which,

Figure 1 is a plan view of a meter embodying my invention;

Fig. 2 is a front elevation of the upper portion thereof;

Fig. 3 is a plan View of the same, with the cover of the meter removed;

Fig. 4 is a front elevation of the same, with the cover removed and a portion of the front wall of the meter case, including the registering mechanism, broken away;

Fig. 5. is an enlarged view of means for adjusting the tangent post radially and angularly with respect to the crank shaft;

Fig. 6 is a plan view and Fig. 6*"is an end elevation of the tangent arm of the meter;

Fig. 7 is a section on the line mm Fig. 5,

' showing the tangent arm and adjusting screw in section and also showing the movable tangent post mounted on the tangent arm and a portion of the indicator;

Fig. 8 is a plan View of, the tangent anchor;

Fig. 9 shows a section of the tangent anchor on the line yg Fig. 8;

Fig. 10 is a section on the line zz Fig. 1, showing a peep hole and marker; and,

Fig. 11 is a plan view of the peep hole and marker shown in Fig. 10.

Referring more particularly to the draw ings, 1 is the ordinary meter casing having the inlet 2 and the outlet 3. 4 is the cover of the meter secured thereto in the ordinary way by solder. 5 is a removable. screwth-readed closure for closing an opening 1n the cover of the meter. 6 is a bushing havmg a transparent closure 7 constituting a peep hole for observing the indicator hereinafter referred to. 8 is a marker supported from any convenient stationary surface, preferably from the bushing 6, and being in a position adjacent to the indicator. I 9 is a perforated stud secured to the cover 4 adjacent to the closure5. The closure 5 is provided with a series of perforations 10. 11 is a seal wire passed through one of the perforations l0 and through the perforation 1n the stud 9 and secured by a seal 11 for sealing the closure 5 in place.

Referring to the parts beneath the cover 4, 12 is the ordinary valve casing, through which extends the crank shaft 13 carrying the ordinary worm gear 14 operating the shaft 15 of the indicating mechanism 16 in the ordinary manner. To the top of the crank shaft is rigidly secured a tangent anchor 17. This tangent anchor is provided with a stud 18 on which is mounted a tangent arm 19. The tangent arm 19 is mounted so as to be movable about the axis of the crank shaft to which the tangent anchor is rigidly secured. The tangent anchor is proagainst longitudinal movement relatively thereto, and is provided with screw-threads which engage the screw-threads in the stud 20. It is also provided with an angular head 24 to which a suitable wrench can be applied,

25 is the base of a tangent post having a'- bearing pin 26 toiwhich the flag arms 27-28, carried by the flag wires 2930, are connected. The tangent post is provided with a screw-threaded hole through which an adjusting screw '31 passes, as shown in Figs.

3, 5 and 7. This-adjusting screw is'provided Witlran angular head 32 to fit a suitable wrench and at its other end passes through a stud 33 carried by an oifset on the tangent arm 19'. This end of the screw 31'is provided with stops 34.-34 on each side of the stud 33, so as to prevent it from moving longitudinally relatively to the stud 33. The tangent-arm carries a horizontal indicating circle 35 having graduations visi ble on its upper surface and lying beneath the marker 8, so that both the indicator 35 and the marker 8 arevisible through the peep hole, as shown in Figs. 10 and 11. 36

is the ordinary pawl for. preventing backward rotation of the meter.

It is to be noted that the heads 22 and 32 are located adjacent to the closure 5, so that when, the closure 5 is removed they are easily accessiblethrough the opening in the cover. By applying a suitable wrench to the head 32, the screw 31 can be moved in one direction or the other, and the tangent base 25, together with its pin 26, can thereby be moved toward or away from the axis of the crank shaft so as to be adjusted readily. The screws may also be provided with holes 22 and 32 in which a rod may be inserted for turning them. The turning of the screw 22 in one direction or the other moves the tangent angularly in one direction or the other with reference to the crank shaft and the tangent anchorage-17 rigidly-connected thereto. By

25 these simple means, therefore, the tangent post of the meter can be adjusted both radially and angularly upon the removal of the closure 5 without disconnecting the meter from the mains or removing it from the place where it is installed. Before and after adjusting, the condition of the meter can be accurately observed by connecting a suitable testing apparatus to the outlet port thereof and observing the indication aflord ed by the indicator 35through the transparent closure '7, the marker 8 constituting a stationary pointer to assist in the accurate reading of the indicator 35. The indicator 35 is rigidly connected to the tangent arm to so that there is no lost motion between it and the crank shaft, and thereby gives a correct indication of the angular position of the crank shaft.

My improvement may be easily applied to old meters by substituting the tangent anchor 17 and the parts carried thereby for the old style of tangent, and providing the cover witha suitable closure and peep hole,

as shown, without altering any other portion of the casing of the meter or the mechanism contained therein.

In using a meter embodying my invention,

I first disconnect the outlet port from the house service, and connect thereto a suitable testing apparatus. I then test the meter,

observing the indications afforded by theindicator 35 through the peep hole, and determine whether it is running fast or slow. If it is not running correctly, I then remove the closure 5 andoperate either the screw 22 or the screw 31, or both of them,-so as to adjust the tangent post into the proper position relative to the crank shaft, testing the meter after such adjustment to determine 635 whether or not the adjustment has been correctly made. I then place the closure 5 in place, sealing it as shown. I preferably place a protecting plug in the peep hole as shown in dots in Fig. 10, so as to protect the transparent closure 7.

The screw 31 is located at one side of the tangent arm 19 parallel to the arm of the tangent which carries the tangent post, and being ofi'set in this way, is accessible for adjusting the tangent post without removing he flag arms therefrom. The tangent post being partly carried by the tangent arm and partly by the screw 31, and having a large bearing urface on the tangent arm, is not liable to be thrown out of plumb when being adjusted toward or from the axis of the crank shaft.

My invention, as will be evident to those skilled in the art, permits'of various modification without departing from the spirit thereof or the scope of the appended claims. The form shown, however, is the form pre-- ferred by me.

What I claim is:
